Palliative fractionated radiotherapy for bone metastases clinical and biological assessment of single versus multiple fractions.
BACKGROUND Radiotherapy is effective in controlling pain from bone metastases which is a direct result of bone resorption. The urine resorption marker DPD proved important in assessing effectiveness of palliative radiotherapy to bone metastases. There is still controversy about the optimum adopted fractionation regimen. The aim of this study is to compare single fraction 8Gy with the standard t...
متن کاملThe Glasgow prognostic score: Useful information when prescribing palliative radiotherapy
The purpose of the present retrospective study was to investigate whether a score reflecting systemic inflammatory processes [the Glasgow Prognostic Score (GPS)] provides relevant information for radiation oncologists. GPS is a three-tiered score [0: normal C-reactive protein (CRP) and albumin; 1: one abnormal result; 2: increased CRP and low albumin]. Correlations between disease type and exte...
متن کاملPredicting prognosis of short survival time after palliative whole-brain radiotherapy
Using existing prognostic models, including the Graded Prognostic Assessment (GPA), it is difficult to identify patients with brain metastases (BMs) who are not likely to survive 2 months after whole-brain radiotherapy (WBRT). The purpose of this study was to identify a subgroup of patients who would not benefit clinically from WBRT. We retrospectively reviewed the records of 111 patients with ...
متن کاملWhole brain radiotherapy for brain metastasis
Whole brain radiotherapy (WBRT) is a mainstay of treatment in patients with both identifiable brain metastases and prophylaxis for microscopic disease. The use of WBRT has decreased somewhat in recent years due to both advances in radiation technology, allowing for a more localized delivery of radiation, and growing concerns regarding the late toxicity profile associated with WBRT. This has pro...
متن کاملBrain metastases: fractionated whole-brain radiotherapy.
Brain metastases are the most common malignant adult intracranial tumors, occurring in approximately 10-30% of cancer patients, and generally lead to a poor prognosis. The incidence has been steadily rising, likely due to longer survival from newer systemic therapies and increased utilization of magnetic resonance imaging. Historically, whole-brain radiotherapy has been a standard of care for t...
